Geometry Optimization of Dispersed UMo Fuel for Light Water Reactors
Nuclear Engineering and Technology, 2023 The Uranium/Molybdenum metallic fuel has been proposed as promising advanced fuel concept especially in the dispersed fuel geometry. The fuel is manufactured in the form of small fuel droplets (particles) placed in a fuel pin covered by a matrix.

Application of the Source-Jerk method using a neutron generator in a subcritical reactor
Acta Polytechnica, 2023 This paper describes the application of the Source-Jerk method using a neutron generator in the VR-1 reactor. The experiments were carried out on a shutdown reactor with subcriticality greater than -10 βeff.

Testing of the ABBN-RF multigroup data library in photon transport calculations
EPJ Web of Conferences, 2017 Gamma radiation is produced via both of nuclear fuel and shield materials. Photon interaction is known with appropriate accuracy, but secondary gamma ray production known much less. The purpose of this work is studying secondary gamma ray production data

Small Modular Nuclear Reactors
, 2020 Small modular reactors (SMRs) encompass a large number of technologies at different stages of development. A key challenge for SMR stakeholders is the evaluation of SMR competitiveness with respect to large reactors (LRs). SMRs are usually considered less competitive than LRs because of a misguided application of the economy of scale principle. However,

Neutron capture cross section and capture gamma-ray spectra of 89Y
EPJ Web of Conferences, 2016 The neutron capture cross section of 89Y was measured by the time-of-flight method in an energy range from 15 to 100 keV. A pulse-height weighting technique was applied to derive the capture yield.

A simple model of reactor cores for reactor neutrino flux calculations for the KamLAND experiment [PDF]
, 2006 KamLAND is a reactor neutrino oscillation experiment with a very long baseline. This experiment successfully measured oscillation phenomena of reactor antineutrinos coming mainly from 53 reactors in Japan. In order to extract the results, it is necessary

Constraints on Hidden Photons Produced in Nuclear Reactors. [PDF]
Physical Review Letters, 2018 New light vector particles-hidden photons-are present in many extensions of the standard model of particle physics. They can be produced in nuclear reactors and registered by neutrino detectors.
